Helge Backhaus, Denis Martin, and Hans Wippel attended this year’s IEEE Conference on Local Computer Networks 2009 in Zurich. There they presented a demonstrator based on research of the 4WARD and G-Lab project, as well as the IME graduate school (Fig. 1). The demo was created together with Lars Völker, Peter Baumung, and Benjamin Behringer. Selected concepts of the demonstrator include the des...

PURPOSE To systematically review and assess the use of the Ligament Advanced Reinforcement System (LARS; Surgical Implants and Devices, Arc-sur-Tille, France) for posterior cruciate ligament (PCL) reconstruction. METHODS A search of multiple databases was conducted using the following terms: (LARS[All Fields] AND posterior[All Fields]) OR (LARS[All Fields] AND PCL[All Fields]). The methodolog...

This development provides a formalization of directed graphs, supporting (labelled) multi-edges and infinite graphs. A polymorphic edge type allows edges to be treated as pairs of vertices, if multi-edges are not required. Formalized properties are i.a. walks (and related concepts), connectedness and subgraphs and basic properties of isomorphisms. This formalization is used to prove characteriz...

Purpose Laparoscopic gastrectomy is accepted as a standard treatment for patients with early gastric cancer in Korea, Japan, and China. However, duodenal stump leakage remains a fatal complication after gastrectomy. We conducted a prospective phase II study to evaluate the safety of the new technique of laparoscopic reinforcement suture (LARS) on the duodenal stump. Materials and Methods The ...
